00:46 NotWorthCr4p how many coulombs does it take to launch a squirrel into next wek?
00:46 rue_mohr hey I'm back
00:46 e_mohr r
00:47 NotWorthCr4p orlok, does it ever stop feeling wierd to run puters with no monitors, keybds, or mice on them?
00:47 rue_mohr distractions
00:48 rue_mohr kat, you ARE interested in the power supply, aren't you?
00:49 tWorthCr4p didn't lose *inter
00:49 rue_mohr kat, I have tonnes of them
00:49 rue_mohr applienaces
00:49 orlock NotWorthCr4p: i find the opposite.. any PC that requires a screen/keyboard/mouse hooked up is either for playing games, or broken
00:49 tWorthCr4p
00:49 NotWorthCr4p or irc, i spose?
00:49 NotWorthCr4p email?
00:49 orlock NotWorthCr4p: and any computer thats doing anything important should be sealed away in a computer friendly enviroment away from people
00:50 NotWorthCr4p true
00:50 Jak_o_Shadows ssh is a wonderful thing
00:50 orlock NotWorthCr4p: i run my IRC client on a computer i have never seen that doesnt actually "exist" as a bit of hardware
00:50 Jak_o_Shadows I should get an IRC bouncer working
00:51 NotWorthCr4p orlok, but don't you need to see what the irc program is telling you i am typing?
00:51 NotWorthCr4p oh,, you are remoting the keybd, mice and monitor
00:52 NotWorthCr4p i am not even doing that atm
00:52 orlock NotWorthCr4p: oh yeah - with the exception of my "desktop" but the main app i run on my desktop can run on any device with minimal resources
00:52 orlock at home in front of windows gaming PC? Fire up putty
00:52 orlock at work on a desktop built from bits of trash? xterm and ssh
00:53 tWorthCr4p
00:53 orlock whatever i am sitting in front of is just a thin client to the important computers
00:53 Jak_o_Shadows So are you saying you do X11 forwarding?
00:53 orlock but you are right about one exception
00:53 orlock at work i run Thunderbird as an email client on my desktop
00:53 orlock Jak_o_Shadows: nah, X 11 forwarding very very rarely, all my work is done via web apps (not often) or remote shells
00:54 Jak_o_Shadows ah
00:54 orlock thunderbird and meld are two apps that i run locally, thats about it
00:54 Jak_o_Shadows I like GUI's a shade too much for that
00:54 Jak_o_Shadows That, and I have no idea how to use screen
00:54 NotWorthCr4p i usually wanna see what each puter is doing periodically
00:55 orlock ctrl-a and n for next, p for previous, c for create
00:55 orlock ctrl-a d to detatch
00:55 orlock screen -r to re-attach once detached
00:55 Jak_o_Shadows I normally X11 forward xterm shells
00:55 NotWorthCr4p and it's easier to kill a process in more ways by using the kvm, at least to me
00:56 NotWorthCr4p it's different buttons <shrug>
01:08 rue_bed orlock, sounds like ratpoison
01:08 rue_bed I know yeske
01:08 rue_bed worked with him
01:08 rue_bed cool guy
01:08 orlock eh?
01:18 NotWorthCr4p "Fuelled by military fuel JP-7, the scramjet engine of X-51 is designed to run for five minutes (300s)." <<== that's 440 miles , in 5 minutes
02:10 mrdata 2.3 km/s ?
02:10 mrdata about mach 7?
02:10 mrdata didnt someone just recently beat that?
03:30 rue_mohr power outage, bye!
03:52 anonnumberanon Anyone know what episode of Ghost in the Shell that was where the security terminal says everything it does, so I can download it real quick and seek to the relevant part? I wanna know if they made it themselves or if they used a library to make the voice.
10:50 quintopia ice
12:42 NotWorthCr4p mrdata , i think the russains are movng faster : yrs ago the usa, them, nasa, etc collaborated on hypersonic stuff, the usa pulled out (for money reasons?), so atm the usa is caught with their pants down (again?)
12:42 NotWorthCr4p iirc, the usa once had some ABM that pushed faster, but they got disallowed under some treaty
12:44 NotWorthCr4p it was the era of the supersonic passenger plane development, the usa built the valkyrie bomber, the russians built something, France/England built the passenger plane, Boeing built models, etc etc
12:52 NotWorthCr4p the X-15 flew faster, but it was a pure rocket
12:54 NotWorthCr4p iirc, one russsian fighter reached mach 3 at low altitude, but took only a few minutes before it ran out of fuel or the engine melted
12:55 NotWorthCr4p the usa's blackbird runs fast, but only above 60,000ft
12:56 NotWorthCr4p russia has 16 TU-160s possibly still flyable
13:02 NotWorthCr4p the russians keep trying for low altitude speed (who knows what they have accomplished now?) prolly because no matter how fast you are flying at 60,000ft, you are still 12 miles away from the target
13:08 NotWorthCr4p location, location, location, i think an Ai and robots should volunteer as peacekeepers in Somalia, trading land ownership for services, it's a place that's sparsely populated, oceanside, lots of sunshine, tons of international trade nearby, and potential for tourists at the offshore islands
19:51 rue_house oooh
19:51 rue_house mty
19:51 rue_house my
19:52 rue_house there is one heck of a storm giong around,
19:52 rue_house i need to fix my upsesssess
19:55 rue_house http://www.ebay.ca/itm/131217538065 <-- looksa that! audio adapters for oscilloscope probes!
19:55 rue_house finally I can use my scope probes with my amplifier to listen to audio
19:56 rue_house ok what do I use for a battery box..
20:05 orlock eurgh wtf
20:05 orlock remote exploit in bash?
20:29 rue_house ok I fixed the gutter leak...
20:29 rue_house yet another use for construction adhesive
20:46 rue_house ok, one upsSsSesS upgraded
20:46 rue_house I gave it an extra upgrade, its had its beeper amputated :)
20:56 NotWorthCr4p It is now 1945 and the Porter eventually found itself patrolling the seas off Okinawa where it was fighting off Japanese kamikazes, blasting several out of the sky. A kamikaze approached the Willie Dee and it successfully shot it down,
20:56 NotWorthCr4p but the plane was moving so fast that when it went into the water, it continued to moving underwater towards the ship. It moved directly under the William D. Porter and exploded, lifting the ship out of the water.
20:56 NotWorthCr4p Only known case of a plane blowing a ship out of the water by "flying" under the ship.
21:18 NotWorthCr4p Logistics firm DHL is using a drone to fly parcels to the German island of Juist, in what it says is the first time an unmanned aircraft has been authorized to deliver goods in Europe.
21:19 NotWorthCr4p Its drone - the "parcelcopter" - can fly at up to 65 km (40 miles) an hour. It will deliver medication and other urgently needed goods to the car-free island of Juist, off Germany's northern coast, at times when other modes of transport such as flights or ferries are not operating.
21:19 NotWorthCr4p For the Juist project, Deutsche Post has received permission from the German transport ministry and air traffic control authority for a restricted flight area that will be used only by its parcelcopter. The drone will also not fly over any houses
21:19 NotWorthCr4p The craft has four rotors, weighs around 5 kg and can carry loads of up to 1.2 kg. Its flight is completely automated, although it will be monitored from the ground and, depending on weather conditions, the 12 km trip to Juist will take 15-30 minutes.
21:19 NotWorthCr4p Flights to the North Sea island, home to around 1,700 people, will start from Friday, weather permitting, and will continue until the middle or end of October, the spokeswoman said.
21:20 rue_house kat, shall we register a team for the power supply?
21:20 rue_house I kinda finished something today, I'm feeling descent
21:21 rue_house or maybe I'll just go make an eprom programmer or soemneting
21:21 NotWorthCr4p up to you
21:22 NotWorthCr4p like i said, *i* don't need or even particularly want the 450vdc psu i am building to run the invertor project, but i can use 1/2 of it in the design i was going to start this winter anyhow, and my project, as you know, is 1/2 the google project
21:23 NotWorthCr4p i was going to feed 225 in to make 120vac, exactly half google specs
21:24 NotWorthCr4p i was going to make short term surge good for 100 amps tho, i got the meters, igbt's, caps, toroids, etc etc etc
21:24 rue_house I seem to be slipping into a nap
21:24 NotWorthCr4p i could just make my project, then put two back to back and use it towards the google prise <shrug>
21:24 NotWorthCr4p of course you do
21:29 tWorthCr4p ponders the boxes of switcher parts from arc wel
21:32 NotWorthCr4p aahh that was a test, wasn't it?, i should have said "hell no!"
21:34 rue_house eeek noded off
21:34 rue_house I'm gonna go sit in th shop
21:37 m_itx puts a thumbtack in rue_house's rue_shop c
22:25 NotWorthCr4p http://money.cnn.com/2014/09/24/technology/security/bash-bug/
22:32 rue_house nobody doing anything properly uses bash for network operations
22:32 rue_house bash is only used for a network program if the program is a hack
22:33 rue_house kat, its just a scare article
22:33 rue_house prolly origionated from microsoft somehow
22:33 NotWorthCr4p it scared orlok
22:33 rue_house well he should know better
22:33 orlock its not trivial, but i'm unsure if its exploitable via ssh
22:34 orlock anything thats vulnerable to it from a web page point of view is probably vulnrable to a pile of other stuff
22:34 orlock because seriosuly, who uses cgi these days
22:35 Jak_o_Shadows I have a bunch of bash scripts I use so that the less technical people who access the server (still via ssh) can do stuff
22:36 orlock woo i think my sitemap cramming works
22:37 orlock i just took every suburb and postcode in the country and combined them with all of our product types
22:37 rue_house I'v noticed that the jukebox is responable for 90% of the shops white noise
22:38 anonnumberanon faraday cage it
22:38 orlock then turned that into a 40+ meg csv to import into the sql server
22:38 rue_house not electrical
22:38 anonnumberanon oh
22:38 orlock school holidays here
22:39 orlock i dont know what colour of noise the bosses kids make
22:39 orlock but damn its annoying
22:56 NotWorthCr4p when the Cortes Bank raises huge waves, how much distance is needed for those waves to dissipate down to background levels?
22:59 rue_house dunno
23:11 NotWorthCr4p scientists say this is a natural Martian occurance : http://static.ddmcdn.com/gif/blogs/dnews-files-2014-09-curiosity-ball-670x440-140924-jpg.jpg
23:18 NotWorthCr4p kool, Tiggr just got directions to Lansdowne Bank (the watery one tween Oz and NZ), and what to expect there
